Hail, severe storms, heavy rain on the way
THUNDERSTORMS, large hail, potentially heavy rainfall and plummeting temperatures are predicted for the coming days on the Sunshine Coast as a new upper trough moves over the region.
Bureau of Meteorology forecaster Harry Clark said the upper trough combined with a surface trough would make for a "fairly dynamic few days".
The upper level low pressure system now lingering over the Sunshine Coast was producing the cold air mass in the upper atmosphere that fuelled instability and increased the chance of thunderstorms.
Mr Clark said a significant new upper trough and surface trough would move into the region over the weekend dropping temperatures and increasing the chance of rain.
He said there would be isolated severe activity during the next few days into the end of the weekend with hail and damaging winds.
"Heavy rainfall can't be ruled out," Mr Clark said.
"It will be fairly isolated - a bit hit and miss - but Sunday should be more widespread as the trough pushes through.
"There was a fair bit of hail last night in Ipswich and the Gold Coast with 3.5 cm hail recorded at Marburg."
Mr Clark said sections of the Sunshine Coast should expect the same in the coming days.
The large upper level system was interconnected with the weather than has also pummelled southern states during the past two days.
By Sunday night's National Rugby League grand final Sydney would be on the more stable side of the system pushing through here and could expect partly-cloudy cool conditions around 18C for the kick-off.
The BOM was also monitoring a category one Tropical Cyclone it has named Liua off the Solomon Islands.
Mr Clark said the system was well north and east of Australia and any potential impact would not be felt for a number of days.
The chance of thunder storms was predicted for this afternoon and evening again into Friday and increasing through Saturday and Sunday.
Temperatures would climb to 25C today, 26C on Friday and 28C on Saturday before dropping dramatically to 22C on Sunday.
Conditions should begin to clear on Monday although it would remain cool and partly-cloudy through to Wednesday when temperatures should climb back to 25C maximums.
